The verdict in three sentences
For a B2B materials trader in Dubai, a vertical ERP (Sage X3, Divalto) gives a proven base but costs 60 to 150 EUR/user/month plus 20,000 to 50,000 EUR of integration, with standard logic that constrains your processes. A custom build means 40,000 to 110,000 EUR delivered in 12 to 20 weeks, modelling your per-customer pricing, warehouses and volume rebates exactly. On a 3-year TCO, the gap narrows from 10 to 12 users, and custom removes vendor lock-in.
Vertical ERP vs custom: cost and scope
Wholesale has dense business rules: negotiated prices, multiple sales units, multi-warehouse stock. Standard covers 70% of the need; the remaining 30% is costly in configuration and bespoke development.
| Criterion | Vertical ERP | Custom |
|---|---|---|
| Licence cost | 60 to 150 EUR/user/month | 0 |
| Initial integration | 20,000 to 50,000 EUR | 40,000 to 110,000 EUR |
| Per-customer pricing | Configurable, rigid | Fully modelled |
| Multi-warehouse | Extra module | Native |
| Bespoke development | Billed at vendor rate | Included |
| Ownership | No | Yes |
| Timeline | 8 to 16 weeks | 12 to 20 weeks |

Mini case study
Sophie runs a materials trader in Dubai: 3 warehouses, 14 users, 900 SKUs. With a vertical ERP at 110 EUR/user/month, she pays 18,480 EUR/year in licences, plus 38,000 EUR of first-year integration.
A custom build at 82,000 EUR models her negotiated per-customer prices and three warehouses natively. Result: 30% fewer order errors on 6,000 orders/year at 12 EUR error-handling cost, i.e. 21,600 EUR/year saved, plus 60 h/month of picking regained (~14,400 EUR/year). With 36,000 EUR of annual gains, custom pays back in 22 months.

Isn't a standard ERP enough for wholesale?
It covers the base, but per-customer pricing and complex volume rebates often need 15,000 to 40,000 EUR of bespoke development that inflates the TCO.
What does accounting and EDI integration cost?
Expect 5,000 to 15,000 EUR to connect your accounting and supplier EDI flows, whether SaaS or custom.
Does custom handle multi-warehouse in real time?
Yes, natively: stock per warehouse, reservations, inter-warehouse transfers and stockout alerts, with no extra paid module.
How fast to a usable first scope?
An MVP focused on catalogue, customer pricing and order entry ships in 10 to 12 weeks, the rest delivered in batches.
How do you cut order errors by 30%?
By combining locked per-customer pricing, real-time stock control and guided validation: entry and pricing errors drop sharply within the first quarter.
